Why doesnt Winplot (Wingeom, etc) let me resize a drawing window?
Windows XP has a feature called show window contents while dragging. This is not a good idea, especially for windows that need a lot of time (relatively speaking) to draw their contents, and it can cause crashes. It is simple to disable the feature; just open the Control Panel|Display|Appearance|Effects dialog box, uncheck the item, then click OK and Apply. Although Windows Vista does not allow the feature to be disabled, it does not seem to cause any trouble. In any event, all my drawing windows can be resized safely using the File|Image Size function.
